GMC G2500 Fuel Tank Problems and Ways to Identify Them

Your GMC G2500 fuel tank supplies fuel to your car's engine, making it an essential part of your vehicle. When you notice a decrease in your car's performance, then it's probably time to check on your vehicle's fuel tank. To help you identify troubles related to your fuel tank, here are a few tips you can try:

Fuel gets contaminated

You car cannot run on contaminated fuel; well, it can but it might stall after a few meters. Fuel contamination is one of the most common fuel tank problems encountered by drivers. Some of its symptoms include a rough idle, loss of power, stalling, and premature failure of the fuel pump and fuel injection. When you start noticing these signs, it's best that you check your fuel tank immediately.

Failure in starting the vehicle

If water gets into your fuel tank, then the most probable result is the occurrence of water in the fuel lines, especially when the car is in use. If water is allowed to settle and freeze in the fuel lines, then it may cause failure when starting the vehicle or worse, sudden stopping of the car while you're driving. When this happens to you, make sure that you remove the water immediately as it may damage the fuel lines as well.

Clogged fuel injectors

Some old vehicles still have fuel tanks made of galvanized steel. When water enters the tank, it settles at the bottom. Because of this, corrosion may form over time and damage the fuel tank. Moreover, the rust from the tank may get sucked into the fuel lines and gum up the fuel injectors. To confirm if your fuel tank has corroded, inspect the tank visually for signs of rusting or flaking.

Slow fill or restricted gas filling

Some vehicles, like the 2005 Ford Mustang, have an inherent flaw that prevents proper filling of the fuel tank. This defect prevents the tank from taking in more than half a tank of fuel. You may also find it odd that the fuel tank is slow to fill. Another sign is the repeated shutting off of the gas station's hose pump. However, this problem is not limited to Mustangs. It's also common in some vehicles, and is usually caused by a faulty vapor venting system inside the tank.
